crystals

Aim: To learn about a saturated solution and how to make crystals

Definition of solution
A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated:
Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)


In groups of three you will make three different types of crystals and compare the results.

Borax Crystals

Ratio; 3 Tablespoons Borax per 1/2 cup water
Materials

1) A cup or a glass
2) pipe cleaner
3) Borax
4) Popsicle stick
5) string
6) warm water
7) spoon
Process

Step 1: Grab a cup or glass
Step 2: Put 3 table spoons of borax and 1/2 cups of water
Step 3: Add all ingredients in to cup 
Step 4: Mix it together with your Popsicle stick
Step 5: attach the string to the stick
Step 6: Make a star with your pipe cleaner
Step 7:  attach the star to the string
step 8:  Put your star into the borax and solutions

Sugar Crystals

Grow your own Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water
Materials

1) A cup or a glass
2) Popsicle stick
3) string
4) warm water
5) spoon
6) sugar
Process

Step 1: Grab a cup or glass
Step 2: Put 3 table spoons of sugar in the cup
Step 3: Add all ingredients in to cup 
Step 4: Mix it together with your Popsicle stick
Step 5: attach the string to the stick
Step 6: Put your string into the cup


Salt Crystals
